  • What is the best way to maintain our programming experiences? [closed]

    - by M3HD1
    Possible Duplicate: how do you remember programming related stuff? During my work experiences, I always met many kind of blocking problems with different technologies. When I remember the efforts I spent to find the solutions I become frustrated and want to find a way to keep all in mind. Generally I keep all the project I made in my Hard Drive, and I usually reuse them when I encounter a problem i already encountered. But this is not to really efficient when you reopen your own code and say: Who is the sucker who wrote this code!? I'm thinking to make my own website in which I can post some tutorials / articles about the problems I met and their solutions. So I keep all in mind and help community. Do you think that it will be a good idea or just a loss of time regarding the actual programming forums?

  • How to visualize real time data on Android? [closed]

    - by matarsak
    I want to build and android app that visualizes real time data (2D animation). I set up a UDP channel that get the data, now I want to visualize it. I know that I can use OpenGL ES, but after a few weeks, I dont think that I'm able to learn that. What about Android Processing? Could it be used for an extensive visualization task like this? or is it limited in some way? I've heard it's not hard learn. Any other options?

  • Which C# Book to take?

    - by Fischkopf
    I was searching for a book to learn C#, but now i'm kinda stuck. I found many people asking the same question, and many people gave answers, but there are so many books about C# that it is really hard to decide which one to take. Now i reduced my choice on two books, but I just can't decide between them. Namely, there are: Programming C# 4.0 and C# 4.0 In A Nutshell The first thing I want to know, are these good choices? I'm not completely new to programming, but I just didn't find the right language until know, but i think C# is the one I was searching for. I know all the bassic stuff from Delphi/Java/Python so I think i'm not a complete beginner in programming. Is there anyone out there that read both books and can cleary explain whats the difference between them? I haven't found many reviews and sort of, so I just don't know which one to chose. Or is there any book that is better suiting me?

  • How do I get the wireless card on a Lenovo S205 working?

    - by user206829
    I tried to install 12.04, 13.04, and now 13.10 on the machine and followed all the instructions that made sense that I could find and still have not gotten wifi to work. It keeps it hard blocked for some reason, not sure why and not sure anyone out there either has figured it out because I would have found it on Google. When I boot from the formatted USB drive, I have WiFi and everything working, why doesn't work after the USB drive is removed? What driver is the USB/wubi or whatever using so that I can install it and have things working? I could have used wubi and installed Ubuntu like that, but I want to make this machine a fully dedicated Ubuntu machine. The laptop is a Lenovo S205 in case anyone can help. I really would like to use 12.04 or higher, i don't want to downgrade to an older version of Ubuntu if at all possible.

  • Using multiple servers for hosting [on hold]

    - by foo
    I need help understanding the concept of using multiple servers (for hosting at home). More specifically multiple WAMP servers. (I have tried looking online but have found no good resources, maybe i am searching for for the wrong things to answer my questions) Questions -How do multiple servers work together? -Do they all have their independent hard drives storing different information? and if so, does the server dynamically locate files? -How do shell commands get executed? -How do they share the "load"? i.e. processing power, resources? Please tag links to resources so i may use a reference. Cheers!

  • Convert JSON to HashMap using Gson in Java

    - by mridang
    Hi, I'm requesting data from a server which returns data in the JSON format. Casting a HashMap into JSON when making the request wasn't hard at all but the other way seems to be a little tricky. The JSON response looks like this: { "header" : { "alerts" : [ { "AlertID" : "2", "TSExpires" : null, "Target" : "1", "Text" : "woot", "Type" : "1" }, { "AlertID" : "3", "TSExpires" : null, "Target" : "1", "Text" : "woot", "Type" : "1" } ], "session" : "0bc8d0835f93ac3ebbf11560b2c5be9a" }, "result" : "4be26bc400d3c" } What way would be easiest to access this data? I'm using the GSON module. Cheers.

  • What are the maven-2 best practices

    - by c0mrade
    Hello everyone, Maven is very impressive tool, I've used it for few weeks now and almost every day I learn something new about maven. What do you think are the best practices? I found this relevant on the google http://www.sonatype.com/people/2009/01/maven-continuous-integration-best-practices/ , others are not relevant at all, and maven apache documentation is not good organized so its hard to pick up on things if you don't know what you are looking for. Any suggestions ?

  • Stumped by "The remote server returned an error: (403) Forbidden" with WCF Service in https

    - by RJ
    I have a WCF Service that I have boiled down to next to nothing because of this error. It is driving me up the wall. Here's what I have now. A very simple WCF service with one method that returns a string with the value, "test". A very simple Web app that uses the service and puts the value of the string into a label. A web server running IIS 6 on Win 2003 with a SSL certificate. Other WCF services on the same server that work. I publish the WCF service to it's https location I run the web app in debug mode in VS and it works perfectly. I publish the web app to it's https location on the same server the WCF service resides under the same SSL certificate I get, "The remote server returned an error: (403) Forbidden" I have changed almost every setting in IIS as well as the WCF and Web apps to no avail. I have compared setting in the WCF services that work and everything is the same. Below are the setting in the web.config for the WCF Service and the WEB app: It appears the problem has to do with the Web app but I am out of ideas. Any ideas: WCF Service: <system.serviceModel> <bindings> <client /> <services> <service behaviorConfiguration="Ucf.Smtp.Wcf.SmtpServiceBehavior" name="Ucf.Smtp.Wcf.SmtpService"> <host> <baseAddresses> <add baseAddress="https://test.net.ucf.edu/webservices/Smtp/" /> </baseAddresses> </host> <endpoint address="" binding="wsHttpBinding" contract="Ucf.Smtp.Wcf.ISmtpService" bindingConfiguration="SSLBinding"> <identity> <dns value="localhost"/> </identity> </endpoint> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="Ucf.Smtp.Wcf.SmtpServiceBehavior"> <serviceMetadata httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" httpsHelpPageEnabled="True"/> </behavior> </serviceBehaviors> </behaviors> Web App: <system.serviceModel> <bindings><wsHttpBinding> <binding name="WSHttpBinding_ISmtpService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" establishSecurityContext="true" /> </security> </binding> <client> <endpoint address="https://net228.net.ucf.edu/webservices/smtp/SmtpService.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ISmtpService" contract="SmtpService.ISmtpService" name="WSHttpBinding_ISmtpService"> <identity> <dns value="localhost" /> </identity> </client> </system.serviceModel>

  • DSOFramer closing Excel doc in another window. If unsaved data in file, dsoframer fails to open with

    - by Steve
    I'm using Microsoft's DSOFramer control to allow me to embed an Excel file in my dialog so the user can choose his sheet, then select his range of cells; it's used with an import button on my dialog. The problem is that when I call the DSOFramer's OPEN function, if I have Excel open in another window, it closes the Excel document (but leaves Excel running). If the document it tries to close has unsaved data, I get a dialog boxclosing Excel doc in another window. If unsaved data in file, dsoframer fails to open with a messagebox: "Attempt to access invalid address". I built the source, and stepped through, and its making a call in its CDsoDocObject::CreateFromFile function, calling BindToObject on an object of class IMoniker. The HR is 0x8001010a "The message filter indicated that the application is busy". On that failure, it tries to InstantiateDocObjectServer by classid of CLSID Microsoft Excel Worksheet... this fails with an HRESULT of 0x80040154 "Class not registered". The InstantiateDocObjectServer just calls CoCreateInstance on the classid, first with CLSCTX_LOCAL_SERVER, then (if that fails) with CLSCTX_INPROC_SERVER. I know DSOFramer is a popular sample project for embedding Office apps in various dialogs and forms. I'm hoping someone else has had this problem and might have some insight on how I can solve this. I really don't want it to close any other open Excel documents, and I really don't want it to error-out if it can't close the document due to unsaved data. Update 1: I've tried changing the classid that's passed in to "Excel.Application" (I know that class will resolve), but that didn't work. In CDsoDocObject, it tries to open key "HKEY_CLASSES_ROOT\CLSID{00024500-0000-0000-C000-000000000046}\DocObject", but fails. I've visually confirmed that the key is not present in my registry; The key is present for the guid, but there's no DocObject subkey. It then produces an error message box: "The associated COM server does not support ActiveX document embedding". I get similar (different key, of course) results when I try to use the Excel.Workbook programid. Update 2: I tried starting a 2nd instance of Excel, hoping that my automation would bind to it (being the most recently invoked) instead of the problem Excel instance, but it didn't seem to do that. Results were the same. My problem seems to have boiled down to this: I'm calling the BindToObject on an object of class IMoniker, and receiving 0x8001010A (RPC_E_SERVERCALL_RETRYLATER) "The message filter indicated that the application is busy". I've tried playing with the flags passed to the BindToObject (via the SetBindOptions), but nothing seems to make any difference. Update 3: It first tries to bind using an IMoniker class. If that fails, it calls CoCreateInstance for the clsid as a "fallback" method. This may work for other MS Office objects, but when it's Excel, the class is for the Worksheet. I modified the sample to CoCreateInstance _Application, then got the workbooks, then called the Workbooks::Open for the target file, which returns a Worksheet object. I then returned that pointer and merged back with the original sample code path. All working now.

  • Access Violation Using memcpy or Assignment to an Array in a Struct

    - by Synetech inc.
    Hi, I wrote a program last night that worked just fine but when I refactored it today to make it more extensible, I ended up with a problem. The original version had a hard-coded array of bytes. After some processing, some bytes were written into the array and then some more processing was done. To avoid hard-coding the pattern, I put the array in a structure so that I could add some related data and create an array of them. However now, I cannot write to the array in the structure. Here’s a pseudo-code example: main() { char pattern[]="\x32\x33\x12\x13\xba\xbb"; PrintData(pattern); pattern[2]='\x65'; PrintData(pattern); } That one works but this one does not: struct ENTRY { char* pattern; int somenum; }; main() { ENTRY Entries[] = { {"\x32\x33\x12\x13\xba\xbb\x9a\xbc", 44} , {"\x12\x34\x56\x78", 555} }; PrintData(Entries[0].pattern); Entries[0].pattern[2]='\x65'; //0xC0000005 exception!!! :( PrintData(Entries[0].pattern); } The second version causes an access violation exception on the assignment. I’m sure it’s because the second version allocates memory differently, but I’m starting to get a headache trying to figure out what’s what or how to get fix this. (I’m currently working around it by dynamically allocating a buffer of the same size as the pattern array, copying the pattern to the new buffer, making the changes to the buffer, using the buffer in the place of the pattern array, and then trying to remember to free the—temporary—buffer.) (Specifically, the original version cast the pattern array—+offset—to a DWORD* and assigned a DWORD constant to it to overwrite the four target bytes. The new version cannot do that since the length of the source is unknown—may not be four bytes—so it uses memcpy instead. I’ve checked and re-checked and have made sure that the pointers to memcpy are correct, but I still get an access violation. I use memcpy instead of str(n)cpy because I am using plain chars (as an array of bytes), not Unicode chars and ignoring the null-terminator. Using an assignment as above causes the same problem.) Any ideas? Thanks a lot.

  • Eclipse vs Netbeans Web Service Tooling

    - by Zenzen
    Some time ago (~4-5months ago) I attented a lecture about JEE and at some point the lecturer started talking about webservices and how hard it is to create a good one because all the IDEs make them in a bit different way (or something like that) and that in general it's better to use Netbeans to create them as Eclipse has some issues, the thing is he didn't really say why Eclipse is bad. Now I'm wondering is what he said true and why, is it really better to use Netbeans for webservices and why?

  • C# WPF fill datagrid or listview from XML file

    - by Dave
    I have a well formed XML file I would like to fill a datagrid with. I would prefer using the AutoGenerate feature of WFPToolKit datagrid, but could hard code the columns in. The trouble I am having is getting the xml file contents into a datagrid. I had it partially working in a listview, but think a datagrid would be more suited for my needs. Can anyone provide a quick example of how to accomplish this? Thanks!

  • What is the easiest x86 Embedded Linux?

    - by QAH
    I want to play around with some embedded linux. I want it to be able to run on an x86 processor (for start, it will be running on my regular PC). I have looked online, but the ones I have found seem hard to setup or lack proper documentation. So what are some good embedded x86 compatible linux distros that are easy to setup or have good documentation on how to get things setup?

  • Javascript new keyword and memory management

    - by Whyamistilltyping
    Coming from C++ it is hard grained into my mind that everytime I call new I call delete. In javascript I find myself calling new occasionally in my code but (hoping) the garbage collection functionality in the browser will take care of the mess for me. I don't like this - is there a 'delete' method in javascript and is how I use it different from in C++? Thanks.

  • Missing makecert.exe

    - by vbori
    For some reason I am missing makecert.exe on my system. I searched the whole hard drive and it's not there. In particular, it's not in C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin where I believe it's supposed to be. I haven't found any articles on this topic on the Internet. Any ideas what's going on?

  • Shoutcast streaming

    - by jn
    hi, im currently working on a app for a podcast (katg.com) which will let you listen live etc... however, i have not found any open source code available to stream shoutcast. I know there are some ways of doing it, but I find it hard to find any available code on the net that explains it for a java/android beginner like myself. Anyone know of any libs/tutorial/examples/code that shows how to do this on android? Thanks JN
